Diagram of how the laser printer uses electrostatics in its work.
Includes explenations for what the different parts of the laser printer do.
Positively charged drum the forms the image.
Types of Negative Charges
- Charge corona wire
The drum is originally positive, it is given a positive charge by a special wire called a charge corona wire which has an overall negative charge from an electric current that runs through it. Not all laser printers use the wire some use charged roller instead but the outcome and process is the same.
Printers are used by offices, businesses, homes, and many more.
